Abstract: A new class of liquid crystal materials has been recently discovered. These mate- rials are constituting of bent core (BC) molecules. Being initially only of scientific interest, now they attract the interest not only of scientists but also of engineers because of their great potential for applications in liquid crystal displays (LCDs) and photonics devices. The present study focused mainly on pure BC nematics and their binary mixtures (BC/RL) with a rod-like (RL) nematic related to thei... more
